Item Synthesis and Characterization of a Quinoxaline Derivative and its Ni (II) And Co (II) Complexes.(Addis Ababa Universty, 2010-06) Amare, Masresha; Chebude, Yonas (PhD)Coordination compounds play vital roles in biology, biochemistry and medicine, controlling the structure and function of many enzymes and their metabolism. They find varied application in many industrial processes and in the development of new materials with specifically designed properties. Thus, synthesis and study of the complexes is very important. In this project work, equimolar quantities of ophenyldiamine and ninhydrine were condensed to produce a quionoxline derivative (NHOPD) which behaves as a bidentate ON donor ligand. The formation of quionoxline derivative (NHOPD) was confirmed by 1HNMR. The ligand (NHOPD) was further complexed with divalent Ni (II) and Co (II) metal salts. Metal complexes of nickel and Cobalt with quionoxline (NHOPD) were prepared and characterized by elemental analysis, conductance measurements, atomic absorption spectra, IR, NMR and UV spectroscopy and magnetic susceptibility measurements. Key terms: Quinoxaline, o-phenyldiamine, ninhydrine, NHOPD
